JAN6418 portable Triode Headphone Amp MkII

The finished portable triode headphone amp/preamp on top of a pair of audio-technica “AIR” head phones and the Cowon S9 in front. This "out of the box" build of the Oatley electronics JAN6418 headphone amp / preamp has a delicious sound, is compact and quite unique. See other images. It may seem odd to be driving high-end headphones with a space age SS player (Cowon S9) with an amp which employs sub-mini valves developed for the military last century. But it sounds excellent. More information about this little tube kit is available on the JAN6418 Valve (Tube) Preamplifier / Headphone Amp Kit page.
